The firt gun in the photo is my 4" co-axail gun pioloted by a one inch sprinkler valve (hevily modified)
The second is my latest and greatest. Its al 2.5 pvc with a standard one inch sprinkler valve that is fired by two 9v in the paintball gun handle.
It has a beer keg regulator inside of the chainber. I just fired it accidentilly at 180 psi (I installed a gauge to prevent that from happening again
The third gun is a confetti launcher that has a custon machined piston that is acuated by a Hevily modified one inch sprinkler valve. The accuall gun can be removed from the stand for storage. The gun is missing the three way top for the streamers in the photo. It is also remotly fired. (They use it at every touchdown)
